What are Security Nuts ?

In simple terms, security nuts are nuts that have as part of their integral design a security feature that once they have been installed, makes them difficult or impossible to remove using standard tools such as spanners.

There are two main types; One way or two way nuts.

security nuts - shear nuts are a one way security nuts

One way nuts such as Shear Nuts are installed and tightened up using a standard spanner or socket set. Once the nut has reached maximum torque (fully tightened), the hexagonal drive head of the nut shears off leaving a tightened cone which cannot be removed.




Kinmar One Way Security Nut with DriverAs an alternative, Kinmar one way security nuts are installed using a special matching one way Kinmar Driver tool, but again, once installed, the nut cannot easily be undone again.






security nuts - scroll nuts are two way security nutsTwo way security nuts are designed so that they can be undone if required after they have been installed. Scroll Nuts are a good example of a two way nut. A special matching driver tool is required to put them on their male threaded counterpart and the same special driver tool is required if you need to remove them again.
